SVA fail - Chadderton
FASTdan - 31/3/09 at 01:27 PM

The day started out bad, but got better!!

We previously had a problem with the twin dellortos where one or two barrels would flood causing a misfire and fuel to poor out of the choke. We 'cured' this by replacing the needles a few weeks back.

However what happens as soon as we start it up to roll into the test lane.....fuel all over the floor and a misfire.The tester (David), as nice as he was said the test could not continue, however after some pursuasion he allowed us 10 minutes outside to try and sort it. Luckily after pulling the top off the carb and messing with the float we seemed to cure it and it held for the rest of the test.

Failures were:

Brake flexis rubbing on suspension

gear knob radii

no anti slip on the brake pedal

a fuel pipe to the carb needs securing

loose engine mounting bolt

loose lock nut on top wishbone

Also had advisories on rear brake inbalance (left to right) and a minor coolant leak at the inlet manifold.

All in all not bad

Easy fix's compared to some!
Soon be sorted and on the road

Just gonna say, would he not let you sort them out as he spotted them?

Yeah they are dead simple but he wasn't really up for sorting things as we went along (despite letting us out into the carpark to play with flamable liquids).

At the time I was thinking we'd need to replace the flexi's anyway - though thinking further I think we'll just secure them to the upper wishbone if there's enough length. We may also have struggled on the gear knob unless he'd let us use tape.

Bit of a bind to go back, but nevermind.

should be on the road just in time for Summer

Nice one

At least you can go back and show him that you have improved the fuel problem as well.

Thats assuming we can sort the damn finicky carbs!

All easily fixed.
Not a bad result really.

They will bend the rule, but they wont break them.
To be fair, the guys I had for my SVA were brilliant. I failed twice before passing the SVA.

Dont worry... Its all part of the journey.

Wow. Easy remedial work for the re-test!! Good fail........

Carbs, sounds like too much pressure 2-3 lbs is all they need, too much pressure will push the fuel past the needle and seat.
Put a new filter on the fuel line you may be getting small dirt particles from and new tank and build dust.

Agreed ^^^ on fuel perssure. Also check that the float isn't sinking.

The rest are easy fixes (no none-slip is a schoolboy error, as are loose nuts). Dave did mine last year and he was good and fair (but failed me). You probably used up all your "good will" by flooding his nice clean floor.

Soon be back for a pass.

I once had an issue with either a Weber or Dellorto (had lots of carbs on grassers in the past so it's not me being particularly thick and not remembering what make I had) with a tiny split/hole in the float resulting in the float sinking. Worth checking!

Did they look at the Mushroom being pinned to the hub, as I am undecided whether I should do this


owelly - 31/3/09 at 05:38 PM

The secondary fixing of the mushroom seems to be a Beverly trait! If you intend taking yours to Beverly, drill, tap and use a grub screw or similar!
